Abstracts


Date Nov 8, 2024

Speaker Patricia Sorya

Title Bounding non-integral non-characterizing Dehn surgeries

Abstract A Dehn surgery slope p/q is said to be characterizing for a knot K if the homeomorphism type of the p/q-Dehn surgery along K determines the knot up to isotopy. I discuss advances towards a conjecture of McCoy that states that for any knot, all but at most finitely many non-integral slopes are characterizing.


Date Nov 15, 2024

Speaker Mike Wong

Title An introduction to Morse homology

Abstract In this talk, we will outline how Morse theory can recover the CW homology of a smooth, finite-dimensional, closed manifold, with a view towards Floer homology.
